ETI-IELBERT A. RUSDEN, OF PROVIDENCE, RHODE ISLAND.

ROLLER WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 470,828, dated March 15, 1892. Application filed May 21, 1891. Serial No. 393,562. (N o model.)

To a/ZZ whom, t may concern.-

Beit known that I, ETHELBERT A. RUsDEN, of the city of Providence, in the county of Providenceand State of Rhode Island, have invented certain new and useful Improvements in Roller Washing-Machines; and I hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in roller washing-machines in which textile fabrics are washed.

The object of this invention is to produce a roller washing-machine which will more thoroughly wash and squeeze the fabric passing through the machine.

The further object of the invention is to produce aroller washing machine which will be more economical in its operation than the washing-machines heretofore manufactured.

Figure l is an end view of the improved .roller-washer, showing the positions of the rolls. Fig. 2 is afrontview of the same. Fig. 3 is a detail view, partly in section, of a part of the nip-roll, compression-lever, and bearing for the same. Fig. 4 is a vertical view of one of the face-plates and bearings for the lower roll, showing the shaft of the same journaled therein.

Similar numbers of reference designate corresponding parts throughout.

In the drawings, 5 5 indicate the end frames, which support the driving-roll 6 and the niproll 7 above the tank 8. The driving-roll 6 is carried on the shaft 6, journaled in the long bearings 62 62, secured to the frames 5 5. At one end of the shaft 6 are secured adrivingpulley 9, over which a belt passes to drive the rolls, and a loose pulley 9', onto which the belt may be shifted.

The upper portions of the frames 5 5 are provided with the slots 5 5, having guides in which the journal-blocks 10 10 are free to move vertically. The blocks are provided with the long journals 10 10 to receive the ends of the shaft 7 carrying the nip-roll 7, and against which the ends of the shaft are held by the yoke-straps 102, secured in studs on the journal-blocks.

The side frames 5 5 are secured together at their upper ends by the stay-rod 11, passing through the tube 12, the ends of which iit into recesses formed in the butt-ends of the removable bearings 13 13, which pass through perforations in the side frames 5 5 and on which thel weighted compression-levers 14 14 are pivoted,projections 15 and l5 being provided on the end frames between which this pivoted end moves.- The removable bearings 13 13 have the shoulders 16 to bear against the inner side of the projection l5 and the end 17, which fits into a socket in the projection 15f, thus allowing the nuts l1 to be tightened without binding the pivoted endy of the compression-levers 14.

The adjusting-screws 18 18 are pivotally secured in the upper ends of the journalblocks.10 10 and are provided with the handwheels 19 19, by which they are turned. These screws operate through blocks journaled in the compression-levers 14, having screw-threaded perforations to fit the screws. They are also used to lift the journal-blocks 10 10, carrying the nip-roll shaft and lifting the nip-roll 7 away from the driving-roll 6. By turning the hand-wheels 19 19 the levers 13 are brought down onto the studs 2O of the end frames. The continued turning of these wheels in the same direction will then lift the journal-blocks 10 10 and the nip-roll 7.

The cross-beams at the lower portions of the side frames 5 5 support the pin-rack 21, between the pins of which the roped cloth passes. This rack is secured by the Straps 22 22, having perforations through which the pins 23 pass to engage with other perforations 24 24 in the rack-beam. A number of these perforations are provided in each end of the rack-beam in order that it may be secured in different positions in its length to vary the wear of the cloth on the nip-roll and drivingroll by guiding the cloth to different portions of the roll. As the cloth passes through these washing-machines in rope form, this is animportant improvement.

' The ends of the tank 8, in which the washing-liquid is contained, are provided with circular openings 25, Fig. 4, into which the ends of the lower roll26 extend. These openings are closed on the outer sides by faceplates 27 27, having the -central circular flanges 28 to serve as seats for the removable bearings 29 29, which are secured therein by the set-screws 30 and into which the ends of the shaft 26', carrying the roll 26, are journaled.

The rolls used in this roller-washing 1nachine are covered with any ordinary waterproof coating which will not be affected by the liquid used to wash the cloth.

The washin g-inachine is usually surrounded by a screen, which is supported by the frames 5 5 and which prevents the liquid from being splashed on the surroundingr objects.

The cloth a b passes into the machine and between the driving-roll G and nip-roll 7, thence under the lower roll 26 and upward between two of the pins in the pin-rack, again over the driving-roll 6, and so continuing until the length of the rolls is covered, when it finally passes between the rolls G and 7 and then ont of the machine. As it is necessary to deliver the cloth in as dry condition as possible, the placing of the nip-roll 7 in the position ott the center of the driving-roll G is very important; also, from the fact that the liquid forced from the cloth will have more of a tendency to flow down back of the drivingroll instead of creeping through between tho rolls G and 7, as would be the case if the niproll 7 was placed directly over the center of the driving-roll.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a roller washing-machine, the combination, with the frames 5 5, having bearings (52 G2, in which the shaft 6', carrying` the driving-roll 6, is journaled, and having the slots 5', in which the journal-blocks 10, carrying the shaft 7' of the nip-roll 7, moves vertically in a direction oft the center of the drivin g-roll of the Weighted lever 14, pivoted on the independent bearing 13, fitting over the stay-rod' 11 and having the shoulder 1G, butting against the outer surface of the projection 15, adapted to prevent this end of said lever from being compressed between the projections 15 and 15', and the adj Listing-screws 18 1S, carried by said levers and pivotally secured at their lower ends to the blocks 10, the hand-wheels 19, by which said screws may be turned, and the studs 2O of the frames 5, adapted to support the levers 14 when depressed, as described.

2. In a machine as herein described, the combination, with the bearing 13, fitting over the stay-rod 11 and having a socket into which the end of the tube 12 fits, a shoulder 16, butting against the outer surface of the projection 15 of the frame 5, the end 17, bearing against the surface ot a recess provided in the projection 15', and the nuts 11', adapted to secure the whole, of the lever 14, pivoted on said bearing between the projections 15 and 15', as described.

3. In a roller washing-machine, the combination, with the tank 8, having the circular perforation 25 cut through the ends thereof to allow the ends of a roll 26, having the shaft 26', to extend therein, of the face-plate 27, having the flange 2S and the removable bearing 29, itting therein to receive the end of the shaft 26 and adapted to be secured by the setscrew 30, as described.
